Perko Fuel System Locking Insert

Protect your investment this season and protect against siphoning and fuel theft. This locking insert is made for 1-1/2in Vented fills, but can fit most other brands as well. It has a black plastic with a zinc alloy lock cylinder and a dual purpose key that opens fill caps and locks inserts.

I have a problem neighbor who is capable of property damage...a little insurance...but it will also keep gas thieves flustered...although 4 screws around the filler are there to be removed and defeat this but it would be obvious and time consuming...
